Hi, I am a male who had one encounter with a commercial transsexual. I received protected anal penetration from her/him. However, we both had unprotected oral sex, and I performed unprotected insertive anal sex on her/him. I also released my semen inside of her/him. I know I wasn't being rational, but what's done was done. So, I'd like to move on to damage control.
I would like to know:-
1. If I'm infected by any STIs, how long would the first symptoms (if any) appear to show?
2. How long after the encounter before I should go for STI tests?
3. If so, what are the STIs I should test for?
I understand that I might be a tad paranoid, but I believe it's better to be safe than sorry.
